905c1600b1 compositor: Set blend functions in ::negotiated_caps() instead of ::fixate_caps()
The latter should not change any state but just fixate the caps, while the
former is always called when srcpads caps are decided.

14c9e37fdd videoaggregator: plug caps leak

or returning it with 2 references to it.

cf6a36721b videoaggregator: properly handle interlace-mode restrictions
videoaggregator can't handle interlace-mode changes so it must
always restrict itself to the first interlacing mode it receives.

Tests included

92245ec05f videoaggregator: repect the result of find_best_format in the default update_caps
We weren't using the result of find_best_format at all.

Also, move the find_best_format usage to the default update_caps() to make
sure that it is also overridable.

3d0f8cfc21 tests: compositor: drop special case for valgrind timeout
The default one is 6 minutes, the test was using 5 minutes so just
resort to using the default.

For the non-valgrind test also use the default 20 secs instead of
reducing it to 6s. No real reason to set a custom value here.

86d21e9455 videoaggregator: fix caps queries to allow proper renegotiation
When caps are already negotiated it should be possible to
select formats other than the one that was negotiated. If downstream
allows alpha video caps and it has already negotiated to a non-alpha
format, caps queries should still return the alpha caps as a possible
format as caps renegotiation can happen.

Includes tests (for compositor) to check that caps queries done after
a caps has been negotiated returns complete results

f1323fb6df videoaggregator: don't do caps processing that is not overridable
Allows the subclass to completely override the chosen src caps.

This is needed as videoaggregator generally has no idea exactly
what operation is being performed.

- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
  gst_videoaggregator_update_src_caps() as we need some of its info
  for proper caps handling.
- Pass the downstream caps to the update_caps vfunc

895e71e810 videoaggregator: Fix mixup of running times and segment positions
We have to queue buffers based on their running time, not based on
the segment position.

Also return running time from GstAggregator::get_next_time() instead of
a segment position, as required by the API.

Also only update the segment position after we pushed a buffer, otherwise
we're going to push down a segment event with the next position already.

ac503aee7d videoaggregator: fix caps query to properly handle alpha formats
Only accept alpha if downstream has alpha as well. It could
theoretically accept alpha unconditionally if blending is
properly implemented for handle it but at the moment this
is a missing feature.

Improves the caps query by also comparing with the template
caps to filter by what the subclass supports.

f1f8e465f2 compositor: Ensure all arguments to CLAMP are signed int
If any of the arguments to CLAMP are unsigned integers, the comparison causes
an automatic conversion of the signed int to unsigned, which causes -1 to become
UINT_MAX and get clamped to the high value of the CLAMP instead of 0.

See 716 at http://c0x.coding-guidelines.com/6.3.1.8.html

Also add a test for this.

f12ef34410 compositor: Actually use the output resolution for clamping
The obscured check in compositor was using the dimensions of the pad to clamp
the h/w of the pad instead of the output resolution, and was doing an incorrect
calculation to do so. Fix that by simplifying the whole calculation by using
corner coordinates. Also add a test for this bug which fell through the cracks,
and just skip all the obscured tests if the pad's alpha is 0.0.

81a78449d5 glvideomixer: swap control binding proxy
The ref_object and object parameters were the wrong way around.

For the typical use case where an application is setting a
GstControlBinding on the returned ghost pad:
1. our control binding would be removed when the new one was set
2. sync_values calls were not being forwarded from the internal
   pad to the ghost pad.

If an application attempts to perform other control binding
operations (get_* family of functions) on the internal pad, they
will also be forwarded to the ghost pad where a possible
GstControlBinding will provide the necessary values.
